冷凝防倒吸的洗干一体机 技术领域
本公开涉及洗干一体机技术领域，例如涉及一种冷凝防倒吸的洗干一体机。
背景技术
随着科学技术的发展和经济水平的提高，越来越多的用户开始关注并选择洗干一体机，如图1所示，洗干一体机的烘干过程主要是，烘干加热管加热产生热量，烘干风机将烘干加热管产生的热量通过烘干加热通道吹入内筒，热量使衣物的水蒸发变成蒸汽，这些湿热蒸汽进入冷凝器冷凝成水。
在相关的洗干一体机及干衣机烘干过程中，对湿热蒸汽主要有三种冷凝方式：第一是使用自来水的冷水，将湿热蒸汽冷凝；第二是使用压缩机，应用压缩机原理使用制冷剂将湿热蒸汽冷凝；第三是空气热交换器，使用外界空气，将湿热蒸汽冷凝。
采用自来水冷凝方式的洗干一体机在烘干过程中，湿热蒸汽在冷凝器中冷凝形成水滴，其中，一部分水滴会被风机吹向冷凝器内壁，沿内壁下流，由于风量较大，还有一部分水滴会被直接带入烘干风机中，吹到加热管上，甚至直接进入内筒，对烘干效率造成影响。

具体实施方式
实施例一
如图2-图8所示，实施例一提供一种冷凝防倒吸的洗干一体机，包括干衣系统，该干衣系统包括外筒11、烘干壳体12、冷凝器13、加热管14和风机15，其中，参见图3，外筒11、烘干壳体12和冷凝器13相互连通构成循环通道。可选地，参见图2和图4，烘干壳体12设置于外筒11的外壁上，并沿外筒11的长度方向延伸，加热管14设置于烘干壳体12内，烘干壳体12一端敞口，该端敞口与外筒11一端相连通，烘干壳体12上设置有风机安装孔121；冷凝器13设置于外筒11没有与烘干壳体12敞口联通的一端，冷凝器13为水冷凝器，冷凝器13由竖直部和水平部构成L型，冷凝器13的竖直部上设置有与外筒11相连通的外筒接口131，冷凝器13的水平部上设置有风机接口132，该风机接口132与上述烘干壳体12上的风机安装孔121相连通，风机15固定于风机安装孔121和风机接口132中。
风机15远离加热管14的一侧设置有挡片18，且挡片18位于循环通道内。在本实施例中，参见图4-图6，挡片18垂直连接于冷凝器13的水平部的内壁上，可选地，挡片18为直线型结构，挡片18一端与冷凝器13的内壁贴合并通过螺钉固定，挡片18没有与冷凝器13的内壁贴合的一端沿垂直于冷凝器13内壁的方向向冷凝器13内部延伸；可选地，在挡片18的螺钉孔181周围设置有加强筋182，通过设置该加强筋182可以提高螺钉孔181的强度。可选地，挡片18与冷凝器13的内壁一体成型，一体成型的结构不仅方便成型、制造简单，而且还能提高结构的整体强度和稳定性。
本实施例提供的冷凝防倒吸的洗干一体机的烘干过程如下：加热管14加热产生热量，风机15将加热管14产生的热量通过烘干壳体12与外筒11连通的敞口吹入外筒11内，热量使衣物的水蒸发变成蒸汽，蒸汽通过外筒11与冷凝器13的竖直部连通的外筒接口131进入冷凝器13，蒸汽在冷凝器13内冷凝成水滴，其中，一部分水滴会被风机15吹向冷凝器13内壁，沿内壁下流，由于风机15风量较大，还有一部分水滴会有向风机15运动的趋势，通过挡片18的设置可改变冷凝器13的器壁的表面切应力的方向，参见图7和图8，冷凝器13的器壁的表面切应力由图7中的A方向变为图8中的B方向，从而调整了该部分水滴的流向，避免该部分水滴在风机15的作用下吹到加热管14上，因此， 避免损耗加热管14的寿命，提高了烘干效率，减少了额外的耗能，并且，挡片18的结构简单，成本低廉，装配容易，解决了相关的洗干一体机工作工程中，湿热蒸汽在冷凝器中冷凝形成水滴，由于风量较大，一部分水滴被直接带入烘干风机中，吹到加热管上，甚至直接进入内筒，对烘干效率造成影响的问题，有很大的推广价值。
可选地，本实施例提供的冷凝防倒吸的洗干一体机还包括注水盒16和设置于注水盒16上的透气管17。洗干一体机在洗漂过程中，由于透气管17连接注水盒16，注水盒16与外界空气连通，因此，能够确保筒内外通气，进水时筒内外的气压保持平衡，能够有效检测筒内进水水位。
实施例二
如图9-图10所示，实施例二中与实施例一相同或相应的零部件采用与实施例一相应的附图标记。为简便起见，仅描述实施例二与实施例一的区别点。区别之处在于，在本实施例中，挡片18设置于烘干壳体12的风机安装孔121处，挡片18为弧形结构，烘干壳体12的风机安装孔121处设置有该挡片18，且该挡片18为不大于180°的圆弧形，挡片18上端与风机安装孔121的孔壁相连，挡片18下端经过冷凝器13上的风机接口132后向冷凝器13内部延伸，挡片18与烘干壳体12通过连接件连接。可选地，挡片18与烘干壳体12通过焊接连接。，可选地，挡片18与烘干壳体12采用一体成型制造。
